I know it's the common opinion that ARL/DO are bad, but I like the rawness of the performances and the directness of the sound. For example, on the post-reunion live albums the guitars are often too reverb-y imo. ARDO is unadorned and VERY live.
It's not my common opinion. I love the rawness and viciousness of the sound on ARLDO. It's one of my favorite Maiden live albums, even without Adrian.
